Some of that 10% could also be essentially unexplainable, meaning that there is variance that ultimately comes from things like electrons bumping around during fetal development and measurement error.

The seminal work is "The Nurture Assumption" by Judith Rich Harris. Inspired by an article (by same author) that challenged the interpretation that Geoffrey was pretending to make. Classic
